Applicatib'nfiled'May 15, 1925, Serial No.

This invention of improvements in tube frames forholdingspools of tuftyarn for use inlooms for weaving tufted pilefabrics and in spoolstherefor relates firstly to' the tube frames Which being adapted forreceiving and holding spools of tuft yarn are provided with guide tubesfor tuft yarn and with engaging parts for engagement with anddisengagement from carrying chains for conveying the tube'frame's andspools of tuft yarn in due order to and from the places-at which theyare required to be used for the supply of tuft yarn for insertionbetween warp threads and also provided with parts for enabling them tobe engaged and held by mechanism by which the tube frames are removedfrom the carrying chains and made to insert tuft yarn between warpthreads and to causetuft yarn to be drawn off the spools and are heldduring the severance of the tufts inserted between warp threads from theyarn on the spools and are afterwards restored-t0 the carrying chains.The invention relates also to the spools for use in tube frames asaforesaid. This invention consists in part in end platesor brackets fortube'frames as aforesaid which tube frames placed in pairs or rows endto end to be operated-simultaneou'sly and in alignment-for theproduction of tufted fabrics of any required width by mechanism providedin looms for seizing the tube frames and disengaging them from thecarrying chains, and holding and moving them so as thereby tointroduce'tuft yarns between warp threads and to draw portions oftuftyarn from the spools and to hold such portions taut while the portionsinserted between warp threads are severed from theyarn on the spools andafterwards restoring the tube frames to the carrying chains.

The invention consists further in the formation'in ea'ch'of the endplates or brackets for a'tube frame of a notch or channel countersunk orr'abbeted in part or wholly to receive and to afford bearing for a pivotwith a" flange or head anclthe provision of a catch or hook on the endplate or bracket for bold ing a pivot in the notch or channel whichensures that a spool inserted in an end plate or bracket of a tube frameshall be securely held therein against-accidental displacement whilebeing easily inserted therein and being easily withdrawn therefromwithout the use of tools and provide simple and convenient brakes forpreventing spools from 30,644, and in Great Britain Ma 14, 1924.

being turned excessively in'the tube frames. The invent-ion consistsfurther in pivots with heads-or flanges at each end of spoolsenablingthe spools, besides beingmounted securely in'the end plates or bracketsof tube frames; to serve as stays for holding'the end plates or bracketsagainst bending or movement on the parts to which they are at= 'tached.I The formation of end plates or brackets for tube frames and of spoolsaccording to this invention is illustrated in the accompanying drawingin which F ig; 1- is a front elevation and Fig. 2 is a sideelevationof'a tube frame with end plates or. bracketsand a spool mountedin it and Fig. 3 isa planof partsshown in Figs. 1 and 2. Fig. 4 is aperspective View of the inner face of a tube frame endplate seenobliquely from the rear. Fig. 5 is a rear elevationof a tube frame endplate The samenumerals' of reference indicate corresponding partsin allthe figures.

As shown in the accompanying drawing; anend plate 1 for use in or withatube frame is'formed as to itsmainbody asa flat plate to" presentaplane surface 'on the side turned away from'the spool 2 mounted,

in the tube frame, Theplate 1' is provided, with perforations or holesin the formation of a projection?) to'be provided on it or for lightnessor other purposes or for the attachm'ent of parts tothe plate 1. I

Theplate'lis adapted in the-part 4 in its general plane to beinsertedj'betwee'n the sideplates of links of a carrying chain and isprovided with a projection 5for engagement with a holder, whichprojection 5px tends in hook like form in the general difrecti'on'of theplane of the end plate 1 and at the rear or side turned towards the backofthe loom when the tube frame is removed from the carrying chains tosupply tuft yarn for insertion between warp threads. and is made topointdownwardly when-the carrying chain supporting the tube framepresents such" tube frame to the holder.

The projection 5 is made tonarrow towards its end so as'to lit thecorrespondingly" narrowing notchor recess in the holder. Projections 6,7, extending laterally from the face of the end plate 1 to be turnedtowards a spool'2- in the tube frame in order tore:

of the hook 11 passing through them The hole and notch in theprojections 3.

that the part lies crosswise of and a little obliquely to the length ofthe end plate 1 so that the engag ing part of the hook 11 for passingover the late of a chain moves in an are slightly oblique to the endplate 1.

The hook 11 is provided with pro ection. 12 hereinafter for 10 areform-ed insuch posit-ion a tail or simplicity called the tail 12toreceive pressure for disengaging the hook 11 from the plate'of a Asshown the tail 12 of a hook 11 is made to project from the face of theend plate 1 turned towards a spool 2 mounted in the tube frame. A platespring 13 secured by a screw 1 1 to the end plate 1 is made to extend bya bent portion over and to present a projection 15 entering the notch ofthe car so as to hold the hook 11 in that notch and to bear by its freeend against the back of the hook 11 so as to press the engaging part ofthe hook never a plate of a chain. The upper part of the project-ion 5serves also to receive contact of part of the device exerting pressureon the tail 12 of the hook lland so enables that device to hold the endplatel in'a holder presented to it. End plate 1 by its outer faceadjacent to the projections 6, 7 presents a surface by which a holdingpart at the side of a loom may cause a tube frame to be gripped in thecase of a I 100m in which one tube'frame is used at a time or may causetwoor more tube frames to be pressed together endwise in the case ofaloom in which two or more tube frames are used in line by means of acurved or a cam like surface provided on a holding part.

The end plate is formed with a notch or channel 16 open at one end andprovided with a wall 17 inclined relatively to the general surface ofthe end plate 1 so that a pivot 18 with a conical head expandingoutwardly, in the case shown a wood. screw, in-

serted in'the end of a spool 2 may be received within the notch orchannel 16 and made to receive bearing in the circular portion of the,notch or channel 16 while not protruding from the end plate 1 and beingheld against withdrawal longitudinally.

A- resilient hook or catch 19, in the case shown a plate spring, securedon the inner face of the end plate 1 by a pivot 20'riveted in the endplate 1 is formed with a notch 21 which may be made to embrace the shankof the pivot 18 in the end of a spool 2 and 1 is provided on the sidecorresponding notch 23 in the end plate 1 so that it may be held therebyagainst being accidentally turned to release the pivot 18. The catch 19is made to bear againsta spool 2 when the pivot 18 is inserted in' theend plate 1. and to act as a brake for controlling the turning of thespool 2 in the tube frame. Fig. 5 shows the catch 19 bowed by itsresilience into the form which its presents in the absencevof a spoolwhile Fig. 1 shows the catches 19' held in a flattened condition by theends of a spool inserted in the tube frame. 7

Two end plates 1 of the formation hereinbefore described but of oppositehand in the formation and disposition of the parts formed on or appliedto them are provided for use at the opposite ends of a tube frame.

End plates provided according to this ,invention enable tube frames tobe applied close together end to end in lines of any length which it maybe requisite to use in a loom of any width and are also easily held withsecurity and precision in the parts by which they are moved fromcarrying chains and moved in the places or place of use in a loom. andmoved back to carrying chains. 7 7

Var ations may be madein the formation of'end plates for tube framesaccording to this invention. For example the hooks for engaging carryingchains may bedifierently mounted in or on'the end plates, as for looexampleby being mounted, cachin two holes;

modification in they formation of'an end plate the notch may be formedwith a ledge around its, wall. and the pivot of a spool for insertion init may be formed with a flange or collar to engage with'that ledge whilenot protruding from the end plate. Again the catch provided on an endplate may be contrived or furnished with a part to enter or to fill thepart of the notch not occupied by a pivot therein or other means forholding the catch in engagement with a'pivot may be provided. i
